This is one train of thought that I like in theory but have a hard time living by.
Reason being is that typically at this age most of the rubber components / hoses/ and belts (unless you have documentation of otherwise) are typically due for replacement.
I think you can get many trouble free miles from a diesel with fresh fuel hoses and filters, coolant, thermostat, and hoses, new drive belts, and all new vacuum lines.
It is also good measure to just replace the flex discs and driveline center bushing/bearing.
I like to attack suspension clunks as they come up and try to only repair what is needed since I find the original MB parts to be of much higher quality than new replacements.
